feat: add recharts library and implement PointProgressionChart component for historical views

- Added recharts dependency to package.json for data visualization. - Implemented PointProgressionChart component to display team point progression over time. - Updated scoring-system.md to reflect completion of historical views and added implementation notes. - Created unit tests for PointProgressionChart to ensure correct rendering and data handling. - Developed season completion detection and percentage calculation functions in season-helpers.server.ts. - Added tests for season completion logic and point progression data formatting. - Enhanced league loader to fetch necessary data for current season and teams.
